Initially, Roose thought about going undercover as a banker, but as an English major who dropped an economics class after three weeks and a name that was easily Google-able, he switched gears and decided to shadow young bankers for three years as they left college and started their careers on Wall Street. His book, Young Money, is about what it's like to work as a junior banker in the largest financial institutions in the world, and how Wall Street's culture and recruiting efforts have shifted in the post-crisis era. I spoke to Roose while he was in town this week promoting his book.
